A clearing device, an operating method thereof, and a cutting device are provided. The clearing device includes: an operating platform, including an operating surface; a first clearing unit, provided on a side of the operating platform close to the operating surface; a control unit, configured to communicate with the first clearing unit and control a clearing operation and a count of the operation of the first clearing unit; at least one detecting unit, provided on the operating platform and communicatively connected to the control unit, wherein the first clearing unit is configured to clear a foreign matter on the operating surface, the detecting unit is configured to detect a degree of cleanliness of the operating surface and send to the control unit a data signal which reflects the degree of cleanliness of the operating surface.

The process relates to the manufacture of a plurality of glazings of complex shape from a rectangular sheet of float glass of large dimensions. The process includes at a first station for cutting the glass sheet, scoring at least one cutting line corresponding to at least one ready-to-shape edge of the glazings; a first breaking operation; at a second cutting station, scoring at least one cutting line corresponding to at least one other ready-to-shape edge of the glazings, and a second breaking operation.

A method for processing a transparent workpiece includes forming a contour of defect in the transparent workpiece and separating the transparent workpiece along the contour using an infrared laser beam. During separation, the method also includes detecting a position and propagation direction of a crack tip relative to a reference location and propagation direction of an infrared beam spot, determining a detected distance and angular offset between the crack tip and the reference location of the infrared beam spot, comparing the detected distance to a preset distance, comparing the detected angular offset to a preset angular offset, and modifying at least one of a power of the infrared laser beam or a speed of relative translation between the infrared laser beam and the transparent workpiece in response to a difference between the detected distance and the preset distance and between the detected angular offset and the preset angular offset.

Methods and apparatus for separating a glass sheet are described. An apparatus and a method utilize a vent bar having a cushion that exerts a force on the glass sheet adjacent a vent line to break the glass into two pieces at the vent line. The edge of the glass sheet has excellent perpendicularity without subsequent grinding and/or polishing so that the glass sheet can be used as a light guide plate in a display.

There is provided a display device that is provided with a display panel having a non-rectangular outline that is incorporated in a curved state, the display panel including a glass substrate that is provided in its side along a curving direction of the display panel with an inflection point of an outline formed by at least one of the combination of curved lines or straight lines, and the combination of the curved line and straight line, the glass substrate including a curved portion in an arc-like shape with a first curvature radius in a portion including the inflection point of the outline, serving as an inflection-suppressing region for suppressing a variation in the side along the curved direction, the curved portion being formed to have the first curvature radius more than 5 mm.

In a substrate processing method in which, for a substrate including a first layer made of a glass substrate and second layers made of a material different from that of the first layer and provided on a front surface and a back surface of the first layer, respectively, an intended mark is formed in each of the second layers, the substrate processing method includes the step of irradiating with a laser beam having an energy density capable of processing the second layers but incapable of processing the first layer from one surface side of the substrate, thereby simultaneously forming the mark at corresponding positions on each of a front surface and a back surface of the substrate.

A laminated glazing having at least one cut-out and a method for cutting a laminated glazing, particularly for a motor vehicle, including at least a first glass sheet, a second glass assembled by an interlayer including at least one sheet of polymer material, the glazing further including an insert having a hole delimited by an inner contour, the insert being housed in a recess provided in the interlayer, the method including detecting, by a vision device, the inner contour; calculating a cutting path to be traveled based on the detection of the inner contour; and cutting, by a laser source having a beam, the first glass sheet based on the calculated cutting path.

A sheet-like glass element has a thickness less than or equal to 0.5 mm and an edge with an edge face intersecting opposite glass faces along two edge lines. The edge face has strip-like sections with each one adjoining a respective one of the edge lines. The strip-like sections interface along a boundary line that extends between the edge lines. The strip-like sections have a first section with a width ranging from 2 ?m to 8 ?m and have a first waviness that is lower than a second waviness of a second strip-like section. The second waviness decreases towards the edge line
